Hello. I can't figure out what's hapening with my situation, maybe some of you might get me on the right tracks or make me ask myself the right questions because I'm kinda lost now... Here's the situation : I've been an early hairloss sufferer. I started to loose ground pretty hard at age 20. But after a few years of research on forums, I started the big 3 (dutasteride, minoxidil 5 and nizoral). It did eventually completely stop my hairloss. At a point that I totally forgot about hairloss forums for 15 years and never thought again about my hair until... 15 years later... Now, aged 39, since july 2019, I've been loosing hair like crazy and my hairline is receeding like crazy. I've lost about 3 cm of hairline in one year... I've been to the doctor, done some tests, everything seems fine. I have very low DHT (which is expected with dutasteride) and Testosterone just a bit over the limit. I don't know how these hormones were before as it's my first blood test. I had low B9 so I'm now supplementing with B9 (folic acid) but it doesn't seem to change anything. Other vitamins, thyroid, are ok. I've been to the dermatologist which is supposed to be specialised in hair but he kinda said to me he can't really do anything. Appart from prescribing finasteride and minoxidil he doesn't seem to be able to do much... The only thing that started around the same time is that I started to have massive hives, which is treated by cetirizine successfully (but whenever I stop the hives comes back). The cause, like in the vast majority of chronic hives, is unknown. I've been checking on allergies but all my test were negative. I'm having a really hard time beleving it's the treatments that "stopped working". As my loss has been really sudden and massive. I kinda hoped it was a telogen effluvium or something temporary but it is clearly not... I've started dermapen since 6 months but it didn't change anything. I'm gonna try zix and topical cetirizine but I have moderate confidence in these treatments... Maybe what caused the chronic hives is also causing the hairloss but I can't be sure and moreover diagnosing the cause of hyves is almost always a fail... Do you guys have an idea on the possible cause, or a direction I should look into? Thanks.
